Answer:
C
Step-by-step explanation:
convert option a to the lowest term
10 : 35 = 2: 7 (divide both ratios by 5)
8 : 28 = 2 : 7 (divide both ratios by 7)
convert option b to the lowest term
4 : 10 = 2 : 5 (divide both ratios by 2)
10 : 25 = 2 : 5 (divide both ratios by 5)
option c
divide 40km/h by 60 to convert to km / min
40/60 = 0.7 not equivalent
option d
determine cost of 1 litre
2.3/1.5 = 1.53
determine cost of 7.5 litres
1.53 x 7.5 = 11.5
